To all whom it may concern:

Be it known that I, ELIJAH A.l OVENSHIRE, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Printing-Machine, of which the following is a specification. Y

This invention relates to a machine adapted for printing on a continuous strip and is adapted for printing a tape or for embossing or printingtickets, or color work, or, in fact, any printing which is to` be applied to a strip or ribbon.

One of the main objects of the invention is to provide for automatically feeding the strip being printed and imprint thereon im-A pressions from different forms or plates. Thus, the machine may be provided with a plurality of forms or plates which will be automatically impressed in succession against the strip, so that it is possible to print a single strip from a series of different forms or plates and thereby produce a strip printed with a succession of different notices or cards. If such forms or plates are all identical with each other, the strip will be printed with a succession of the same reading matter or other characters, While if the forms or plates are of different type or character the strip willbe provided with `a series of impressions corresponding to the several different types or characters.

A further object is to provide for assembling such forms or plates in the machine in a magazine, preferably in pack form, wherebythe capacity of the machine is unlimited, that is to say, it will operate continuously and automatically to impress the plates in succession against the strip so long as there are any plates in the magazine, so that the only'manual operation required is to refill the magazine from time to time. Each plate after being impressed against the strip is discharged from the machine.' The order in which the plates are impressed upon the strip is determined by the order in which they are inserted in the magazine.

Referring to the drawings :-Figure 1 is aplan view of the machine. Fig. 2 is a vertical section on line 032-002 Fig. 1. Fig.

4 3 is a "section on line 3-3 Fig. 2. Fig. 4

is. a' section on line :v9-$04 Fig. 2. Fig. 5 is a section on line m5-5 Fig.v 2. Fig.y 6 is a section on line :c6-a3 2. Fig. 7 is a section on line 007-027 Fig. 2. Fig. 8 is a i plan view of the magazine and plate folvof movement at right angles to the line of progression of the strip, the plates being `moved in succession underneath the strip and being pressed up against the underside of the strip by a vertically operating platen 6, each plate being inked before it is moved under the strip. The strip remains stationary while the plate is impressed against the strip by the platen 6 and after the impression has been made the strip moves forward and the plate is discharged from the machine'and another plate takes its place on top of the platen, this operation being repeated successively, the plates being moved one after the other underneath the strip and impressed against the strip and discharged from the machine and the strip being advanced intermittently after each impression.

The strip 5 is fed from a roll 7 on a core 8, the latter being mounted on a shaft 9 which is supported in a pair of notched arms l0 whichl form part of a bracket 11 which is bolted to the table 1. The roll 7 is prevented from turning ahead of the speed of the strip 5 by being slightly retarded frictionally by a pair of friction plates 12 which are adjustably Vsecured on the shaft 9, as shown in Fig. 1. From the roll 7 the strip 5 passes over a supporting rollerf13, also mounted on the bracket Il1, which roller is mounted on la shaft 14, the ends of which are journaled in studs 15 screwed in the bracket 11 and provided with knurled heads for adjusting the bearings of the shaft 14. A tension regulator is provided above the roller 13 and consists of a comb with spring teeth 16 which teeth rest upon the surface of the strip 5, the comb 1G being supported by a cross bar 17. 'The pressure of the teeth 16 upon the strip 5 prevents the latter from being carried forward farther than it is actually pulled. As the strip 5 is advanced intermittently it is necessarily jerked lsomewhat 'and withoutthe tension device the jerk-would be apt to move the strip 'farther than it is positively drawn by the actuating mechanism. From the roller 13 the strip 5 passes under a guide roll 18 supported by a frame 19, thence passes underneath a bed 20, thence under another roller 18, and thence to a guide roller 21 supported by studs 22 similar to the studs 15 and mounted in arms 23. From the roller 21 the strip 5 passes onto a receiving reel 24,. Above the roller 21 is a` strip holder so constructed as to press firmly against the strip immediately above the roller 21 and lhold the strip against rearward movement during the recovery stroke of the strip actuating device to be described, andwhich automatically moves out of contact with the strip to /permit the forward movement of the strip and not impede its movement during the forward stroke of the strip actuating device. This strip holder comprises a blade 25, in thelower edge of which is inserted a strip of padding 26 adapted to make contact with the strip 5, the blade 25 being secured to a frame 27 on a shaft 28 journaled in the arms 23.

One end of the shaft 28 has an arm 29 upon which a downward pull is exerted by 'a coil spring 30. At the other end of the4 shaft 28 is an arm 31 to which is conected a toggle lever 32. The toggle lever 32 is pivoted to a toggle lever 33 which is rigid on a shaft 34. An arm 35 projects from the shaft 34 and is connected with an operating rod 36, the upper end of which slides through a guide 37, the lower end of the rod 36 belng forked and straddling the main shaft 38which acts to guide the' lower end of the rod 36. At an intermediate point on the rod 36 is a roller 39 which is in the path of movement of cam plates 40 and 41, which are arranged substantially diametrically opposite on a cam disk 42 mounted rigidly on shaft 38 and the cam 40 serves to act against the roller 39 to depress the rod 36 while the cam 41 serves to act against the underside of the roller 39 to elevate the rod 36. The cams 40 and 41 are so located on the disk 42 that the cam 41 lifts the rod 36 and fleXes the toggle levers 32, 33 as shown by dotted lines in Fig. 2, thereby lifting the strip holder blade 25 from the strip 5 during the forward stroke of the strip actuating device, while advancing the strip. While, when the rod 36 is depressed by the ca-m 40, the strip holding blade 25 is moved down against the strip 5 and prevents the retraction thereof during the recovery stroke of the strip actuating device. -It will be understood that the spring 30 serves to maintain the'strip holding blade 25 elevated when the latter is not positively depressed by the cam 41 and the object of the cam 40 is to' positively move the blade 25 down and into contact with the strip 5, the spring 30 notbeing depended lpermits them to be manually operated to. lift the strip holdingbla'de 25 at any time irrespective of the position of the parts of the machine when it is desired to free the strip 5 to enable it ,to be withdrawn or moved freely along in the machine. When the toggle levers 32 and 33 are so bent the spring 30 which exerts downward pull on the arm 31 holds the toggle levers 1n this position with the blade 25 raised until such time as the toggle levers are restored to their normal straight position. Thus, with this device it is possible to quickly release the strip 5 and it is not necessary to manuallyv hold the blade 25 elevated as the toggle levers 32 and 33 and spring 30 perform that function.

The receivmg reel 24 has a shaft 44, one end ofwhich is mounted in a stub shaft 45 which is rotatably mounted in a trunnion 46, the latter being externally threaded and screwed in one of the arms 23. The inner lend of the stub shaft has a flange 47 faced '24 and the friction thereof is so regulatedv that while it is sufficient to drive'the reel and pull the strip through the machine, each time the strip is arrested and held stationary by the strip holding blade 25, the flange 47 will slip while the reel 24 remains stationary. As shown in. Fig. 7 the friction between the clutch 47 and flange 49 is secured by a spring 50 which, through the medium of a block 51 in which the other end of the shaft 44 is journaled, pushes the shaft 44 and reel 24 to the left against the friction clutch 47. The block 51and spring 50 are contained within a trunnion 52 screwed in the outer arm 23, The block 51 lhas a headed stem 53 by meansl of` which the block 51 may be retracted to'enable the reel 24 'to be freely spun around when desired to manually wind or unwind the strip on the reel without operating the machine. A grooved pulley 54 is carried on the stub shaft l45 and is continuously driven by a belt 55:4 which runs over idle pulleys 56 and a driving pulley 57 on shaft 38. Thus as the shaft 38 rotates continuously and through the belt 55 continuously rotates the clutch .47, the latter operatesv the reel 24 whenever. the strip 5 is releasedV by the strip holder and when the strip holder retains the strip 5 against movement, the clutch 47 slipswithout actuating a hub 60 mounted on a shaft 61 support-A spherical head. The hub 60v has a lug 71 with spherical head. Projecting Yalso from the hub 68 is an arm 72 having recesses 73, 74 which are adapted to be engaged by a Spring presse-d bolt carried in the arm 59, and the `bolt 75 serves to hold thehub 68 in either of two positions, z'. e., with the blade 64 in contact with the strip 5 or out of contact with the strip 5. A cam plate 76 on the disk 42 serves to operate against the stud 70 to depress the latter and move through the hub 68. Lug 67 and linki66 move the blade 64 out of contact with the strip 5, while a cam plate 77 on the disk 42 serves to act against the lug 70 to rock the hub 68 in the other direction and move the blade 64 into contact with the strip 5. The plate 76 only momentarily contacts with the lug 70 but depresses the hub68 suiiiciently to cause the recess 73 to be engaged by the bolt 75 so that when so engaged the blade 64 is held in Contact with the strip 5, during the stroke of the frame 58, after the cam plate 76 has .left the lug 70`until the lug 70 shall have been acted upon and moved in the other direction by the plate 77 which releases the notch 73 from bolt 75 and link l66 releases blade 64 from the strip Thus, the plates 77 and 76 serve to respectively kick the blade 64 into or out of contact with the strip 5 and the blade 64, after being so shifted, is detachably located in either of said positions during the remainder `of the rotation of the disk. 42. The frame 58 is oscillated by means of a cam 78 mounted on the shaft 38 which acts against the lug 71' in a continuous manner, so that the frame 58 sweeps gradually forward and back. 1n Fig. 2, the frame 58 is shown in dotted lines at the be ginning of its forward stroke with the blade 64 gripping the strip 5, sothat as the frame 58 moves forward the strip 5 will be drawn forward with it, while the full lines indicate vthe frame 58 and other parts of the machine at the position that they have immediately yafter theim ression. When the frame 58 reaches the nd of its outward stroke the cam plate 77 acts upon lug 70 through'the described connections to release the blade 64 from the. strip 5, so that the frame 58 can freely travel to the dotted line position bar against which screw the lug 71 strikes to limit the forward stroke of the frame 58. The frame 58 operates by gravity through its return stroke and is stopped at the end of its return stroke by an adjusting screw 81 in the arm 59, which screw strikes against the table 1, as shown in dotted linesin Fig. 2. rI"he cam 78I is so cut that it will permitthe frame 58 to fall by gravity farther than shown inl dotted lines in Fig. 2 if the screw 81 be adjusted to permit of such further movement, ,hence by adjusting screw 79 to the right and adjusting cani 78 to the right on shaft 38 (Fig. 2) the cam 78 will then act to move the lug 71 farther and thus act-uate the frame 58 farther to the left which,

together with the adjustment* of. screw 81 to permit the farther movement of frame 58 tol the right will result in causing the frame 58 to be actuated through a longer stroke and thereby shift the strlp 5 accordingly.

The plates 4 are arranged in'a pile one above the other in a magazine comprising four vertical angle bars 82 which vextend above the magazine table 3. Extending longitudinally of the magazine table 3 are ways 83 which guide a sliding plate follower 84, the latter having lugs '85 which receive the endof a rock arm 86. Extending laterally from the rock arm 86 is a post 87 which is engaged by a notch 88 in a connecting rod- 89 as shown in Figs. 3, 5 and 1. The front end of the connecting rod 89 is pivoted to a slotted rock lever. 90 which is oscillated by a crank pin 91 which projects from a cam 92 mounted on shaft 88l and as the arm 90 oscillates it acts through the connecting rod 89 and rock arm 86 to reciprocate the plate follower 84. The rear wall of the notch 88 in the connecting rod.89 is shallow as shown in Fig. 3 and a flat spring 93 bears against the underside of the post 87 and under'ordinary conditions holds the notch 88 in engagement with the post- 87. But if for any reason the follower plate 84 should stick in moving forward, the spring 93 will yield and permit the connecting rod 89 to lift and disengage the notch 88 from post 87, so that while the connecting rod 89 will be positively drawn forward the follower plate 84 will not travel forward but remains stationary withthenplunge194 and, raise the platen 6 and im press the plate 4 against the strip 5 while the strip is stationary, the cam permitting the plunger 94 and platen G with plate 4 to drop immediately after the impression, immediately after which the gripping blade 64 carries the strip 5 forwardthe next step. Theiframe 19 #which supports the bed is adj ustable by four screws 99. As each plate 4 is moved forward by the plate follower 84, the plate 4 passes underneath a pair of inking rollers 100 which ink the plate before it is deposited on the platen (i. Each ink roller 100 is supported at each end by a post 101 which projects -up through the table 1 an is slidably mounted therein. 4The lower ends of the posts 101 are secured to a plate 102 which is raised at intervals by a rock lever 103 having an adjusting screw 104, the lever 103 being operated by the cam 92 as shown ter receiving ink from vin Fig. 3. The cani 92 allows the ink rollers 100 to drop so as to ink the plate 4 as it passes thereunder, the cam 92 acting to raise the rollers 100 .during the rest of the time against a distributing roller 105 which in turn receives ink from a roller 106, the lata roller 107, the latter being automatically given 1iongitudinal movement by a lever 108operated by Ya cam 109 driven by a belt 110 from grooved pulleys 111 on shaft 38, ink being furnished to the roller 107 by a plate 112. As each plate 4 is moved onto the platen 6 it pushes off the previous plate which has just made the impression and the plates 4 are thus moved one by one' onto the platen 6, impressed against the strip 5 and discharged from the machine, the strip 5 advancing during the interval between impressions and thusvthe strip 5 is printed with a series of impressions.l
